摘要
高熵材料(HEMs)是典型的结晶、相纯、构型无序的材料,至少含有五种元素,均匀地混合在固溶体框架中。高熵合金(HEAs)和高熵氧化物(HEOs)的发现打破了材料科学的传统观念,为探索新材料、优化性能和追求先进应用提供了途径。虽然对高熵氧化物的研究已经取得了重大进展,但高熵氧化物的创造性突破仍有待揭示。本重点综述旨在建立一个表达 HEM 概念的结构框架,特别强调 HEOs 的晶体结构和功能特性。文章全面讨论了最近的合成进展,这些进展促进了前瞻性成果及其在电催化和电池中的当前应用。此外,该书还揭示了 HEOs 的现有限制因素,重点介绍了采用理论和实验工具应对挑战的方法,同时划定了能源应用领域的潜在探索方向。
High Entropy Oxides: Mapping the Landscape from Fundamentals to Future Vistas
High-entropy materials (HEMs) are typically crystalline, phase-pure and configurationally disordered materials that contain at least five elements evenly blended into a solid-solution framework. The discovery of high-entropy alloys (HEAs) and high-entropy oxides (HEOs) disrupted traditional notions in materials science, providing avenues for the exploration of new materials, property optimization, and the pursuit of advanced applications. While there has been significant research on HEAs, the creative breakthroughs in HEOs are still being revealed. This focus review aims at developing a structured framework for expressing the concept of HEM, with special emphasis on the crystal structure and functional properties of HEOs. Insights into the recent synthetic advances, that foster prospective outcomes and their current applications in electrocatalysis, and battery, are comprehensively discussed. Further, it sheds light on the existing constraints in HEOs, highlights the adoption of theoretical and experimental tools to tackle challenges, while delineates potential directions for exploration in energy application.

期刊介绍:
ACS Energy Letters is a monthly journal that publishes papers reporting new scientific advances in energy research. The journal focuses on topics that are of interest to scientists working in the fundamental and applied sciences. Rapid publication is a central criterion for acceptance, and the journal is known for its quick publication times, with an average of 4-6 weeks from submission to web publication in As Soon As Publishable format.
ACS Energy Letters is ranked as the number one journal in the Web of Science Electrochemistry category. It also ranks within the top 10 journals for Physical Chemistry, Energy & Fuels, and Nanoscience & Nanotechnology.
The journal offers several types of articles, including Letters, Energy Express, Perspectives, Reviews, Editorials, Viewpoints and Energy Focus. Additionally, authors have the option to submit videos that summarize or support the information presented in a Perspective or Review article, which can be highlighted on the journal's website. ACS Energy Letters is abstracted and indexed in Chemical Abstracts Service/SciFinder, EBSCO-summon, PubMed, Web of Science, Scopus and Portico.
